no ALT option under joystick menu

[robit]

Hi guys,
recently I've noticed, that I miss ALT option under joystick menu on one of two sv-d1000 displays. I've tried different screen combinations but no luck to solve this issue. Do anyone have an idea what mybe wrong or I just miss some information. I did a config procedure but nothing changed.
